' HINGE STRUCTURE.

I Application filed. November 18,1926. Serial N0. 149,016.

improve and simplify the construction and operation of hinges of the character V described; to provide a hingehaving a selfcontaining gauge by means of which it may be readily positioned and valigned without the use of squares or like tools; to provide vide ahinge-in whichl the leaves will lie shortened.

` a hinge in which the leaves are offset'with relation Itov eachother both longitudinally andlaterally and inf which a long pintle bearing may be obtained and further to proin a common plane when the hinge is-closed. The hinge is shown by'w'ay of illustration in theaccompanying drawings,.in which: Figure l is a perspective view of the hinge, Figure 2 is a perspective view of one leaf of the hinge, y

`rFigure' showsthe, manner yin whichthe hinge is applied .and aligned'with relation toa door or jamb,

Figure 4 is an end view tially open, y l

Figure is a sectional view'of the hinge showingit applied tol adoor andV jamb and showing the hinge in closedposition7 *of` the hinge Figure Gishows anotherform of the hinge in which'the pintle pin yand bearings are Referringvto the draWings,`in detail, and particularly tov Figure 2, A indicates ingeneral, one of the leaves of the hinge. The leaf lconsists of a bearing plateQI onv the inner edge ofwhich are formed pintle bearings 3.

Formed integral with the outer vedge of the bearing plate is a fastening plate4,` in which is formed a number of hol-es such as indicated at 5, through which screws or like fastening means may beinserted. The beariing'plate 2 onwhich the pintle bearings are vformed is elongated and rectangularin shape and in this instance is t-wice as long as the fastening `plate 4, that is, the fastening plate extendsY from the upperjen'du `of the bearing plate to 'a point midway there- Ofythus leaving halfof the outeredge of the bearing plate free and unobstructed, as

Formed 'between the bearing plate and the fastening platev is'an oset shoulder 7. This shoulder is 4formed in alignment withfthe outer edge 6.of the. bearing plate and c0- operates therewithto for-m' an aligning gaugeto assure perfect valignmentof the bearings 3 Vwith the door orjamb to which the hinge is to be secured; Theftwo leaves formingthe-hinge are indicated at A andv B in Figure l. Theyare identical.inconstrucl tion and inY fact'are formed. by the same. set of dies, that is, the leaves forming the hinge are preferably made Vof sheet metal and asv both leaves are identical in construction, `one set `of dies will suiiice. The .two leaves are assembled asv shownin Figure l and areA connected by the usual form of pintle'pin such Vas `indicated at 8. TheV leaves are thus free tovswing-Witli relationto each otherin 'the-.usual mannerrof butt hinges an'd may be-applied to ordinary doors andas such may be applied to the doors or rooms or theV smaller doorsof cabinets and the like and 1n fact in places Where a butt hinge` '1'nay be employed.' .f

yBy referring to Figur-e 1,.-it will be noted i that when two leaves are assembled, thatit is accomplished by reversing them end for' end. The 'fastening p late4 of one leafwillthus lil) assume'an upper positionfand the fastening leaf 4flof the opposite leaf a lower position andas each fastening platemerely extends lhalfway of the bearing plates, they will align end for endwhen the hinge is closed,

that is, if the leaf A (see Figure l). isfolded over against theleafB, it-will assume the dotted line position indicated-at 9,. and as both of the fasteningplates are-offset by thc forh'iing of the shoulders 7, they will lie in( a common plane, that is, the bearingplatcs 2 will lie on top of each other when the hinge is closed, asshoWninFigure 5, but the fastening plates 4 and 4a' will align endfor end and will furthermore,assume a positionin agcommon plane. y o,

A hinge designed and constructed as here described has ,a number of advantages when comparisonv is vmade with 'ordinary butt hinges. First perfect lalignment Lis" obtained rbetween the 'hinge plate and the jarnb by merely applying it to the j amb as shown in Figurer 3 vand thenfinserting -the fastening Y' screws through the holes indicated at.5 (see Figure 3) and then vsecuring the opposite leaf to the door in the same manner.- In other words, a perfect'alignment is obtained between the door'andjamb when the hinge is applied without the use of squares o r like tools. Second: as thehinge leaf sections are made of sheet metal, it becomes unnecessary to gouge outlthe wood to receive the fastenplates as the hinges lie in a common plane when closed, as shown in Figure f5. lnl other words, the onlys ace that will'be formed between the door :and the jainb D willbe that space occupied by the thickness of a single plate. The plates may, of course, be counter-sunk into thewoodgof the door or jamb if a flush close-fittingjoint is desired, but it .is usuallyunnecessary, particularly when fitting kitchen cabinet doors, locker doors and theflike. Third: by yconstructing the hinge leave sections as shown a single set ofv dies will suilice, as both lleaves are identical in construction. HFourth: vthe length of' therbearings which support the pintlev pin Slis doubled when comparison is y made with ordinary butt hinges and the life ofthe hinge, due to general wear, should lat least be double. Fifth: as the outer edge 6 of the bearing sections and the lshoulder .7

engage-the outer .edge ofthesdoor andjamb tipping ofthe fastening plates withrel'ation to the'doorja'mb is eliminated, 'as agreatj 'part ofthe weight is taken up by the shoulf' ders andthe `free edges Gbearing against the exterior Wood of the door and jamb,

thus relieving the fastening screws of practically all strain.

If it is desired 'toV shorten the length of the pintle pin th'efupper and lower ends of the bearing-plates may be cut away as indicated at 1-2 andk 12a. inFigure 6. .Even when the obtained whenzcomparison is made leaf sections areso cutaway a greater length of. pintle bearing is obtained when comparison is made with ordinary hinges and a savingof material vand reduction in weight is Y with the ystructure shown in Figure l.

While: the hinges here shown are more or less specifically described and illustrated7 IV wish it understoodthat various changes may be resorted to Within the scope ofthe appended claims. Similarly that the materials f and finishes of the several parts employed .edges rwith 'pintle bearings to 'receive the pintle, andan Iattaching plate :extending fromthe outer edge of each bearing plate and offset from the plane of the bearing plate to form an offsetshoulder spaced from the pintle 'bearings to provide an alining gauge and to cause the' attaching `plates to occupy a position in `the same longitudinal plane when the hinge is'fo'lded.
